If you prioritize a larger screen and superior contrast for immersive HDR gaming and media, the Gigabyte CO49DQ's premium price offers top-notch performance, particularly for tasks like HDR video editing or print photo editing due to its color accuracy. However, for casual gaming, productivity, and digital photo editing without the necessity of HDR, the Dell S2721DGF provides good performance at a significantly lower cost. Keep in mind, though, for competitive gaming, the Gigabyte's ultra-wide screen may not give as sharp a response as the Dell. Give Feedback

Christian Eberle | January 2021
"The Dell S2721DGF checks all the boxes for an upper-mid priced display that can take on the best gaming monitors, and you might even be able to find it for under $500 (it's $450-$500 as of writing). The monitor's 1440p, runs at 165 Hz without overclock, has AMD FreeSync Premium Pro and G-Sync Compatibility, covers a large portion of the DCI-P3 color gamut and includes a lighting effect on the back."
